Efficiency of the top-down PAH-to-fullerene conversion in UV irradiated environments
M. S. Murga, V . V. Akimkin, D. S. Wiebe
Polycyclic aromatic hydrocarbons (PAHs) and fullerenes play a major role in the physics and chemistry of the interstellar medium. Based on a number of recent experimental and theor…
Spectral energy distributions of dust and PAHs based on the evolution of grain size distribution in galaxies
Hiroyuki Hirashita, Weining Deng, Maria S. Murga
Based on a one-zone evolution model of grain size distribution in a galaxy, we calculate the evolution of infrared spectral energy distribution (SED), considering silicate, carbona…
Impact of PAH photodissociation on the formation of small hydrocarbons in the Orion Bar and the Horsehead PDRs
M. S. Murga, M. S. Kirsanova, A. I. Vasyunin +1
We study whether polycyclic aromatic hydrocarbons (PAHs) can be a weighty source of small hydrocarbons in photo-dissociation regions (PDRs). We modeled the evolution of 20 specific…
Self-consistent modelling of aromatic dust species and extinction curves in galaxy evolution
Hiroyuki Hirashita, Maria S. Murga
We formulate and calculate the evolution of dust in a galaxy focusing on the distinction among various dust components -- silicate, aromatic carbon, and non-aromatic carbon. We tre…
Modelling the evolution of PAH abundance in galaxies
Shiau-Jie Rau, Hiroyuki Hirashita, Maria Sergeevna Murga
We investigate the evolution of polycyclic aromatic hydrocarbon (PAH) abundance in a galaxy, which is a crucial step to understand the evolution of bright emission features in the…
The Photolysis of Aromatic Hydrocarbons Adsorbed on the Surfaces of Cosmic Dust Grains
M. S. Murga, V. N. Varakin, A. V. Stolyarov +1
The work is devoted to the adaptation of the results of laboratory studies of the laser-induced dissociation of molecules of benzene adsorbed on a quartz substrate to the condition…
